To all whom it nuu concern-.-

Be it known that I, LUDwIe Sol-Ion, a subj ect of the Emperor ofAustria-Hungary, residing at Vienna, in the Province of Lower Austriaand Empire of Austria -Hungary, have invented a new and usefulImprovement in Safety-spouts for Receptacles Containing VolatileInflammable Liquids, of which the following is a specification.

My invention relates to receptacles for keeping and carrying volatileinflammable liquidssuch as spirits, ether, benzin, sulfid of carbon, andthe like; and it has for its object to provide a closing device for theoriiices of such receptacles which in the case of the vapors issuingfrom the receptacle being accidentlly ignited with certainty preventscombustion from spreading into the interior of the receptacles.

According to my invention the inlet and outlet orifices to be providedwith the safetyspout have necks inserted into them, a diaphragm of finewire fabric or finely-holed sheet metal being interposed into each neck.Between the diaphragm and the receptacle the passage or bore of the neckis by preference narrowed and adapted to be controlled by a cylindricslide-valve screwing into the side of the neck, across this latter, andprovided with a conic front end, to which corresponds a seat formed inthe side ,of the passage. The free end of the neck has its outsideprovided with male screw-threads and its inside with femalescrew-threads in order to admit of a cap being screwed on, the cylindricrim of which has female screw-threads, while its central nipple has malescrewthreads. Between the cylindric rim and the central nipple asuitable packing is secured to the ca In t e annexed sheet of drawings,Figure 1 is a sectional elevation of the lower part of a sheet-metalcask the outlet-orifice of which is provided with my safety-spout andFig. 2 is a sectional elevation of a sheet-metal can, into which theinflannnable volatile liquid is allowed to flow from the cask. Figs. 3and 4 are sectional views of a screw-cap and screwstopper, respectively.

It will be seen that a neck or tube is soldered into the outlet-orificea of the sheetmetal barrel 1), the said neck being composed of twolengths c and d, screwed together and finally connected by solder.

Into the inner joint between the two lengths c and d is inserted thediaphragm f, made of fine and dense wire fabric or of finely-perforatedsheet metal. This diaphragm is either made of a metal not subject tooxidation or provided with a coating which prevents oxidation, as itsbeing destroyed by oxidation in only one point would render itineffective.

Between the diaphragm f and the cask I) the passage or bore of the neckis narrowed at gin order to adapt it to be closed by means of a pin orcylindric slide-valve h of greater diameter than the channel g andscrewing into a bore crosswise t0 the said channel. The front end of thepin h is made conical and en ters a correspondingly-shaped seat formedin the side of the passage g. It will be seen that by partly unscrewingthe pin h one may more orless withdraw its conical point fromcorresponding seat, and thereby open the passage to any desired degree.The outer end of the valve 7), is protected by a screw-cap j, providedwith a hole '5, through which a cord or wire 1 destined to carry aleaden seal as, may be threaded. hen such a cord or wire y is used forpreventing the valve h from being opened during transport or storage,the said cord or wire y is also passed through the eye 1:, made integralwith the length 0 of the neo The outer end of the outlet-neck is underordinary circumstances closed by a screwcap 7r, Fig. 3, provided at thecenter of its inside with a screw-threaded nipple Z. To the femalescrew-threads of the rim of the cap correspond the male threads of theoutside of section cl of the neck, while the male threads of the nippleZ are destined to engage the female threads at the inside of the length(Z of the neck. Between the nipple Z of the cap 7c and its rim thebottom of the cap is at m covered with a packing chosen according to thenature of the liquid to be kept in the receptacle. In Fig. 1 it issupposed that this cap 7c, commonly closing the outlet-neck and providedwith a solid bottom, has been removed and replaced by a cap-n, into acentral orifice of whose bottom a spout n is soldered. The lower end ofthe said spout n is again provided with the safety device comprising thetube or neck, consisting of the two lengths c and d and the diaphragmclamped between them.

The can 0, into which the volatile inflammable liquid coming from thecask b is to flow, has its inlet-orifice again provided with the neckconsisting of the lengths c and d, between which the wire-fabricdiaphragm f is clamped and which is adapted to be closed by a screw-capk, Fig. 3, with a central screwthreaded nipple Z. The spout p of the can0, too, has its mouth fitted with. the tubes 0 and d, screwed togetherand clamping the sievediaphragm f. The screw-plug i), Fig. 4, having apacking 11,, secured to its collar, serves' for closing the spout 9.

With the described safety-stopper one may kindle benzin flowing out fromthe spout n and allow it to flow in the burning state into the can 0without any fear of endangering the contents of the can or the cask.

The sieve-diaphragms f in inlet-necks are to advantage made cup-shaped,turning the convex side downward, and provided with a planesieve-flange, through which the air displaced by the liquid which entersthe can or receptacle can escape.

When filling a receptacle provided with the described safety-stop er,care must be taken that the level of the iquid should be placed belowthe sieve-diaphragm. Any surplus liquid poured in inadvertently shouldbe decanted.

tile inflammable liquids, the combination with the tap-hole of anoutwardly-projecting neck, a wire-gauze diaphragm inserted into theouter end of the neck, a spout adapted to be secured to the neck, a wiregauze diaphragm inserted into the outer end of the spout, and a valveadapted to close the said neck between the receptacle and diaphragm,

substantially as and for the purpose described.

In witness whereof I have signed this specification in presence of twowitnesses.
